Y y28 Claims. Thisinvention relates to typographical machines, such asLinotype machines of the` gen-l eral organization represented in LettersPatent of the United StatesNo. 436,532, to O. Mergen- 'tha1er, whereincirculating matrices vare released from a magazine in the order in whichtheir characters are to appear in print and then assembled in line, thecomposed line transferred to the face of a mold, the mold lled withmolten metal to form a slug' or Linotype against the matrices whichproduce the type characters thereon, and

l the matrices thereafter elevated and `returned through` distributingmechanism to the magazine from `which they started.

l More particularly, it relates to machines equipped with a `pluralityofsuperposed magazines containing different matrix fonts and which arearranged to be moved as a unit upwardly and downwardly in the machine tobring one or another into operative relation to the assembling and`distributing mechanisms. In such machines, the magazines areindependently removable and` replaceable and, to thisend, are arrangedtobe spread apart in order to permit access to the magazine to` be removedwhich, for thispurpose, is rst located in operative position. Provisionis also made for` raising the magazine to be removed on its supportingbase frame clear ofthe assembler throat, so that it may be drawnforwardlyby the operator and supported in a vertical position at thefront of themachine` by arms pivotally arranged on the machine frame andadapted tobe swung into a position to supportthe magazine in the mannerstated. The replacement of a magazine is effected by reversing theseoperations.

'I'he pivotally mounted supporting arms are,

permanently secured tov the machine frame and normally located in aninoperative position `alongside of the bank of magazines. `As `themagazine to be removed is located inoperative position, .mechanismassociated i therewith is automatically brought into operative relationto devices operated by one of the pivoted arms, so that, as the arm isswungforwardly intoactive magazine supporting position at the front ofthe machine, such magazine (i. e., the one to be removed) will be liftedto` separate it from its base frame and locate it in a position to clearthe` assembler devices during its removal `from thefmachine. `Andlikewise, in the case` of a replacement magazinagt-he return movement ofthepvoted `arm to inactive position will lower such magazine intothe"base frame, for proper locationfwithrespect to its `assembler devices.

Also, safety elements are provided for locking the pivoted arm againstmovement until the magazines have been properly spread to` permit theremoval of the selected magazine; and other elements are providedfor-locking the magazines to their base frames, the `latter lockingelement being released by the initial movement of the pivoted arm frominactiveposition and being reset in locking position by the` finalreturn movement of the arm to zinactive position.

According to the present improvementsthere is provided a magazinespreading attachment 4 which is entirely automatic insofar` as concernsthe selection of the magazines to be spread apart for the removal of themagazine inoperative position. In other words, regardless of whichmagazine is in operative position, the operation of the device willcause all the overlying magazines, whetherthere be one, two or three, tobe spread apart` from said operative magazine and this without anythought upon the partof the operator. To this end, the base frames areprovided at their opposite sides with laterally extending lugs adaptedto be engaged by a. pair of vertically movable arms for spreading themagazines apart. The arms are mounted, one at each end ofa transverserock shaft, and extend upwardly along the oppositelsdes of the bank ofmagazines rearward of the lugs. The rock shaftand magazine spreadingarms are mounted in the` machine frame independently of the bank ofmagazines, and a hand crank fixed to the rock shaft is operable byforward rotation, rst to move the arms into engagement with the lugs onthe base frame of the magazine (or magazines) above the one in operativeposition, and then to lift the arms vertically for spreading themagazines. The arms areu formed on their forward edges with a, series ofl lugs (three fora bank of four magazines) arranged to engage beneaththe laterally projecting lugs on `the base frames, the lugs onythe armsbeing spaced apart so that, as the arms move vertically, the magazineswill be `lifted and spread progressively, starting with the top-mostmagazine. l l l 1 The present improvements also contemplate a novellinkage between the pivoted `magazine supportingarm and the device forraising the operative magazine from its base frame pre-` paratory toremoval and for lowering thereplacement magazinev backinto position` onthe base frame. The improvedconstruction gives an increased mechanicaladvantage which greatly `facilitates the operation.

The magazine base frames have also been `substantially improved.Heretofore, they were made of iron cast'in a single heavy structurecomprising marginal members and intermarginal crosspieces to providereinforcement for the marginal members as well as supporting elementsfor the magazine and associated mechanisms. Such cast base frames werenecessarily extremely heavy in order to provide the required strengthfor carrying out their intended functions. These heavy units weredifficult to handle during themachining and finishing processes and weresusceptible to breakage because of theessential brittleness of castiron. Furthermore, if such castings are inaccurately formed orimproperly nnished in some respect, the entire unit might be rendereduseless. f

According to the present inventiornthe mag-v4 -the invention is notlimited to any particular form'or embodiment except insofar as suchlimitations are specified in the appended claims,

`The matricesarestored according to font in the superp'osed channeledmagazines A, four of which are shown herein but of which agreater orlless number might be employed, if desired (Fig. 1). The top magazine isof the split variety, i. e.,it has lower and upper sections a and a1,the lower section a only containing matrices, and .the upper sectionalserving to guide the distributed matrices into the proper channels inthe lower section. 'I'he remaining magazines are of the usual fulllength, both varieties of magazines being shown for purposes later toappear. The several magazines `A are removably supported uponseparate-base vframes AA1- oonlmechanism in Ithe usual way. The threeupper base frames A1 are pivoted at their upper ends, by pins'A2, on apair of plates A3, rising from the lowermostpbase frame at the oppositesides thereof, yso that the base frames supporting the respectivemagazines may be spread apartI to permit the independent removal of anyselected magazine.V

, Asbest shown in Figs. 1 and 2, the banksof escapements E are mounteddirectly on the respec'tive magazines. Suchbeing ythe case, it isapparent that beforea magazine can be removed from the machine, it mustfirst be separated from its base frame sufciently tofenable theescapements to clear the assembling mechanis`m C. For this reason, eachbase frame is provided with a central magazine lifting and supportingplate F (see Figs. 4 and 5), which in the` present instance issubstantially as long in a fore-and-aft direction as (theubase frame it`self, the plate being pivotally supported at its upper end in the baseframe on pins F1, -thus permitting it be swung upwardly to lift themagazine. The plate F is formedwwith a1 central fore-and-aft groove F2which accommodates a A correspondingly arranged reinforcing rib (notshown) on the underside of the-overlying magazine. lAt its lower end,the plate F is provided with a stop shoulder F3 which serves as anIabutment to* retain the magazine in place on the plate, when the latteris in its raised position, 'by engaging a transverserib a2 locatedasusual on 'the underside of the lmagazine near the front.

The magazine lifting and supporting plate F, associated with each baseframe, is raised and lowered by anunderlying plate cam or equivalentdevice G fixed to a transverse rock `shaft G1 which isjournalled in thebase frame near the front end of the plate F (Figs. 4 and-5).'

In the normal position of the parts, the magazine raising andv loweringplate Fis supported at its front end vby :the magazine-base frame withthe cam plate G located directly beneath it substantially in the planeof the base frame (see the magazine second from the bottom'in Fig. 4).

However, when the rock shaft 'G1 is turned in a` clockwise direction,looking at the machine from the left, theplate G will engage theunderside of theplate F and cam the latter upwardly, thereby raising themagazine off its base frame to a position in which the escapements Eonthe maga-zine will clear:1 the assembler throat C, thereby permittingthe removal of the magazine (see the lower magazine in Fig. 4). On theother hand, when areplacement magazine has been locatedupon the plate F,a counterclockwise rotation of -the rock shaft G1 will restore the camplate G to its normal position, permitting the magazine and the plate F,by gravity, but under the control of the cam plate G, to be restored totheir-normal positions on the base frame. It will be observed that thecam G is provided, on its active edge, withva hook'shaped piece G2adapted, when' the cam is turnedupwardly,` to engage a pin F4 projectingfrom the right edge'of the overlying plate F and thus lock the latterin` itsproper raised position.

` The transverse rock shafts G1 have a common operating device which isautomatically coupled to the corresponding shaft G1 asthe respectivemagazines are moved into operative position, it `being recalled that amagazine must be so located before it can be removed from the machine.As shown in Figs. 4 to 8, the common device referred-to includes inpart, a rotatable member H supported in a bracket B1 fixed to themachine frame B atthe left of the bank of magazines and located incoaxial alignment with the rock shaft G1 associated with the magazinefinoperative position. The member H is formed in its inner face with agrove H1 Which, in the normal position ofthe parts,'extends in thedirection of movement of the shift frame. .,At `the left end of eachrock shaft G1, there is pinned a collar G3 formed with vertically spacedtongues Gt which. align with the groove H1 when the associated magazineis resting on its base frame. Consequently, as a magazine is raised orlowered into operative .position by the movement of the shift frame,the` tongues G1 on the: associated rockshaft G1 will enter thegrooveHl.. and couple the rock` shaft `and .member H together. If themember H is now turned in aclockwise direction, looking at the .partsfrom the left,.the coupled rock shaft wilL likewise-be turned` in thesame direction to raise the supportingrplate'F and lift thecorresponding magazine oif its base `frame. And similarly, when a`.replacement magazine hasV been locatedfon'` the elevated supportingplate E, ,the return. movement `of the memberI-I toits t `(compareFigs..l ,andfhand see Fig. 5). `Normally, however, the arm K is.prevented from` being moved toits active .position tto:` effect theseparation of `ther magazine` inoperative position from `itssupportingbaseframe until themagazines havebeen spread. `The means forlocking the a1mK..in its normal position areA described later. cn.V`Itvvill` sufncef to say here, `that .the

means referred to are controlled by the magazine unit next `alcove fthemagazine `in operative `position, the arrangementheing such that unlessthe magazines have been` spread, rotation of `the magazine supportingarm K to operative position is prevented., `When the magazines arespread, however, the` locking meansis rendered inoperative, leavingthemagazine supporting arm` K `free torotate.` The magazinesvarelockedon their respective base, frames, each by a pairof spring `latchesM pivotally `mountedon `the base frame to engage the. opposite sideedges of the magazine (Figs.` 7

and 8) The latches M are controlled byla pair of cams G5, oneformeclonthe collar G3, pre viously referred to, and the othercnacllar G6, saidcollars lbeing pinned to the rock `shaft )G1 at itsleft and right ends,respectively.` When the `rock shaft G1 isinits normal position, highportions G7. of .the cams G5hold theflatchesfM inengagement with the.magazine against the N1 which is pinned thereto. of t/he `magazine bank,thereis yprovided a veraction of latchsprings. M1.1 However, `when. theshaft G1 is rocked to 'separate the magazine from its base frame, itsinitial movement (Which is idle as far as the separation of `themagazine from its base frame is concerned) turns the` cams G5 enough tomove the high portions Grl thereof out of engagement with the latches,allowing the latch springs`M1 to rock the latches outwardly from thesolid to the dotted line position shown in Fig. 'I where furthermovement is prevented by the engagementfof the `latches with lowportionsG8 of the cams. The latches are rendered inactive `by .the outwardmovement just referred to, thereby` leaving the magazine free to beseparated from its base frame by the further rotation of the rock shaftG1. When a replacement magazine is `lowered on` to the base frame 'bythe rocking ofthe shaft G1 in the opposite direction, the high portionsGr'I of the cams G5 reengage the respective latches M during the nalrocking movement of theshaft and `force the latches, againstthe actionof the springs M1, into` locking engagement with the opposite sides ofthe magazine. l l

Except as hereinafter indicated, the mecha- .nisms thusfar described maybe found in one Referring to Figs. `1,12 and 3, it will be observed thatbelow the bank of magazines, there is pro-` vid-ed a transverse rockshaft N'journalled in bearings B2 located at opposite sides of the frameB, the shaft extending beyond the outer face of the bearing at the leftto accommodate `a. crank Adjacent each side tical arm N2 formed at itslower end with Van elongated slot N5. through which the shaft N passes,the arm N2 resting, when in normal position, with the upper end of itsYslot bearing against the shaft.` Each ,armNZ `is connected to l theshaftN by a toggle consistingof a crank; arm

. N4 pinned to the rock shaft N andra link N6, the

Near their upper ends, thearms NY2 are formed on their front edges eachwith three spaced lugs N9, N10 and N11, arranged one above the other,and adapted when the mechanism is operated to cooperate with lugs A18projecting from the opposite sides of each of the three upper baseframes.

The magazine spreading mechanism is held in its normal position, asshown in Fig. l, by a spring clip N13 fastened to the machine frame atthe `right and which frictionally engages the crank handle N1. Assumingnow that the operator desires to spread the magazines in order toVremove the one in operativeposition, `he pulls forwardly on the armNlluntil it banksagainst a sto-p N14 fixed in the machine frame. thecrank N1 rocks the shaft N in a clockwise direction, looking at thepartsifrom the left,l kand during `theffirst `st'agesof itsymovement,the arms That movementY of moved upwardly; and since the lugs N9,N111and N11 are located so 'as to underlie theV lugs A18 on the threeupper base frames A1 (assuming that the lowermost magazine is the one inoperative position)v when the forward movement ofthe arms N2 isarrested, the three upper magazines and their base frames will be spreadapart from the lowermost magazine to permit of its remova (Fig. 2).

The mechanism operates in a similar fashion when either the second orthird magazine from the bottom is in operative position, the onlydifferen-ce being that when the second magazine is operative, the twolowermost lugs N9 and N1o on the arms N2 will cooperate with the lugsA18 of the two topmost magazines, the topmost lug N11 being idle;whereas when the third magazine from the bottom is inoperative position,only the lowermost lugs Ng on the arms N2 will be active, the twotopmost lugs N and N11 being idle.

It will be noted from Fig. 2 that when' the arm N1` is full forwardresting against the stop N14, the toggles have moved past the deadcenter position so that the weight of the magazines operates to preventthe counterclockwise rotation of the shaft N. In otherlwords, once themagazines have been spread, they will thus remain until the operatorrestores them to normal position by an operation which is merely thereverse of that previously described, i.'e., by a return movement of thehandle N1 to its normal positiorn To prevent the separation of the armsN2 from the lugs A18, the lowermost lug N9 is formed on its front edgeand at the top'with a lip N12- which, by engaging the lug A13 at thefront, will counteractthe tendency `of the magazines, because of theirweight, to cam the arms N2 rearwardly. Only one set of lugs need beprovided with such a lip, and it is appended to the bottom lugs N9 sincethose lugs will alwaysv be operative when the spreading mechanism -isused regardless of the magazine in operative position.

' Due to the fact that the magazine base fra-mes have their ownindividual pivots at the rear, those that are swung upwardly during aspreading operation will move relatively in a fore-and-aft direction.Accordingly, to permit this motionl to take place freely withoutinterference lbetween the magazine units, provision is made for aprogressive spreading of the magazines. Thus, assuming that the threeupper magazines are to be spread to give access to the lowermostmagazine, the spreading mechanism is so designed that the top magazineunit is moved up clear of the underlying unit before the latter startsto move, and the latter unit in turn is moved up clear of its underlyingmagazine before this last one starts to move.

` To effect this progressive spreading movement of the magazines, thelugs N9, N10 and N11 on the arms N2, While spaced equidistantly .asbetween themselves, are nevertheless spacedV apart l at greaterdistances than are the lugs A18 on the different magazine base frameswhen the latter are in their normal positions. Consequently, when thearms N2 are arrested in their forward movement by engagement with thelugs A18, there will bel just sufficient clearance between the parts topermit the-top of the lugs N11 to pass freely beneath the overlying lugsA111011 the top base frame. `Theclearance between the intermediatelugsN10 and their overlying lug A18 will be greater, while the clearancebetween the lugs N9 and their overlying lugs A18 will be greatest ofall. Accordingly, as the arms N2 are moved upwardly during the magazinespreading operation, they will pick up the magazine units progressivelyin order starting from the top. And,v of course,

when the magazine units are returned to their normal positions, theywill seat one after another progressively starting with the bottom.

YTo complete the description of this phase of the invention, attentionis directed to the fact that the arms N2 are guided in their upwardmovement, on one side by the crank arms N'1 and, on the other side, bycollars N3 which, like the crank' arms N4, are pinned to the shaft N(see Fig. 3).

yAfter the magazines have been spread apart, the next stepin the processof removing a magazine is to raise or separate it from its base frame sothat its associated escapement mechanism E will clear the assemblerthroat C. As stated previously, this is accomplished by rotating thetransverse rock shaft Gl associated with the magazine in operativeposition, the shaft G1 in turn rotating the cam plate G to raise thecenter plate F and consequently the magazine.

vAs previously stated, the shaft G1 is rotated by the movement of themagazine supporting arm K into and out of its active position. It willbe recalled that the rock shaftGl of the active magazine unit isautomatically coupled by a tongue and groove connection to the member Has said magazine unit is brought into operative position (Fig. 7). Themember H is in the form of a sleeve rotatably mounted on a shoulderedscrew H3 threaded into the bracket B1, being formed at the right withthe arm H2 which presents the groove y VH1 and at the left with an armH1 (Figs. 1 and 4).

The arm H4 is formed with an elongated slot H10 to accommodate alaterally extending pin H9 pre- .sented atA one end of a lever arm H7centrally fulcrummed as at Ha andI formed at its other end with a gearsegment H6 which meshes with a gear H5 formed on the hub K15 of themagazine supporting arm K; At vits free end, the magazine supporting armKis equipped With a handle K2 which may be grasped to move the arm intoand out `of its active position. v As previously stated, the movement ofthe arm K from its normal position is prevented unless the magazineshave been spread. The means for the -purpose includes the arm H2 which,in the normal position of the parts, extends upwardly in theY line. ofshift frame movement (Fig. 7). The free end of the arm H2 is formed withan ear 11,1 which extends laterally inward from the arm and normallylies behind the lowermost tongue G4 on the collar G3 fastened attheleft'end of the rock shaft G1 on the base frame next above the magazinein operative position. Hence, before the magazines have been spread, anyattempt to rotate 'the arm K to its active position is prevented by theengagementl of the ear h1 with the tongue G4. However, during theoperation of spreading the magazines, the rock shaft G1 on the baseframe next above the magazine -in operaf tive position is carried upwardso that the tongue G4 thereon will stand clearof the ear h1, leaving thearm K free to rotate. 1

Normally, the arm K extends rearwardly alongside the'bank of magazines,and the arms H4 and H'Voccupy positions at `right angles to one anotheras shown in Figs. 1 and 2. However, as the arm K is swung forwardly intoits active position, it operates through the gear H5 andthe gear segmentHs to rotate the arm I-li7 counterclockwise, looking at the parts fromthe left. The arm H7, in turn, through themedium of the pin H1'` thereonacting in the slot H10 on the arm H4, rotates the latter in the oppositedirection to the position shown in Fig. 4. During the rotation of thearms H'1 and H4, the pin H9 rides from the outer end of the slot .H10 tothe inner end thereof and return as the arms` H7' and H4: move from the.right angular relationship shown in Fig. 1 to the. right mentv of thearm H4 effects a correspondingmovement of the member H to impart a 90rotation in the same direction to the shaft G1, to raisethe magazinefrom its base frame in the manner` heretofore described, through thecooperation of. the cam G and the plate F. vWhen the replacementmagazine has been located on theplate F, the magazine is loweredontoitsbase frame by a return movement ofthe arm Kto its original inactiveposition, the operation `of the `interconnecting parts being the reverseof that just described. l. n

With the foregoing arrangement, `a 180rotation of the arm` K frominactive to active Vposition is utilized to effect the 90"v rotation ofthe shaft G1 y forcing bar on its under `surfaceridingdri the y angularrelationship shown in Fig. 4. Such movein separating the magazine fromits base frame,

thus obtaining a mechanical advantage. of two. Additionalmechanicaladvantage is obtained because of the formation ofthe p1`at`ecam G. y Thus, the plate cam G is bentftransversely` to provide, at thebend, a portion g which, as the cam is rotated,

" rst engages the plate F. Asthe cam G continues v to use it as one of apair of arms for supporting the magazines at the front of the machineduring the removaland replacement operations. this end, the arm K isformed with a pair of ribs K3 and K1 projecting laterally differentdistances from its inner face the lower rib K4 projecting beyond the ribK3 (Fig.` 4). `The ribs K3 and K4 converge at the hub end of the arm Kinto `a single rib whose top surface lies slightly below the plane ofthe top surface of the plate VF when the latter is in its raisedposition. The upper rib K3 extends in the saune plane throughout the`length of the arm, terminating in an upturnjed lip K5. The rib K4, onthe other hand, extends `in the same .direction as the rib K3 butdiverges downwardlt7 therefrom, terminating short of the forward end ofthe arm K in an upturned lip K6` whose free end is sufficiently belowthe rib K3 so asnot to interfere with a .magazine supported on thelatter rib. The companion arm K1 at the opposite side of the bank ofmagazines is With ribs K3 and K4.

i i The 'twopairs of ribs` K3 `andyl, adapt the 3,40 K3 thereof, whereit is pivotally supported in aV identically formed I,arms K and K1 tosupport both full llengtlri maga-f zines1 aswell as the lower sectionsof the4 split variety of magazine, one-ofv which, as stated, is shown asthe top magazine in Fig. 1. `flhus, in removing a full length magazine,such as the magazine shown in thefraised removal position in Fig. 4, themagazine is lifted by hand to disengage the front transverse rib azfromthe `stop `shoulder F3 at the forward end` of the plate F, freeing themagazineso that. it can move forward by gravity guided bythe centralfore-and-aftreingroove F2 in the plate F.I f Asthemagazine slidesforward olfv the plate F, therearmost transverse rib a2 thereof comes.to rest on the ribs K3 4and supports the magazine during the remainderof its `travel until the` rib aZ strikes the.rv lips K5, whence themagazine is .allowed-to pivot on .the rib `in, assuming averticalposition fromrwhich it is manually lifted from `the arms K andK1.` 1 Inthegreplgacement ofl aV magazine, the rearmost transverse` rib a2 of themagazine is set on the ribs K3 in back of the lips K5 with the magazineina vertical position. p Then the magazine is tilted so that it liessubstantially in the plane of the ribs K3 and the plate F and is forcedrearwardll until itV reaches -a positionV where ltsforward end can be`lowered on to the plate Fwith the foremost transverse rib a2 thereofengaged behind the shoulder F3. 'I'he magazine is then in position to belowered onto .its supporting base frame.

With the split variety of magazine, however, the rearmost transverse rib`d2 is not as long (due `to thedivergent shape of the magazines) as therearmost transverse rib of a fulllength magazine. Hence, when thesection a is 1removed. (inthe same manner as already set forth for afull length magazine) its rearmost rib a2 slides along the wider ribs K4and comes to rest against the lips vertical .positionprior to beinglifted from the armsKand K1. o

The magazine supporting arm K1,` at the right of the machine, is movableinto andout of active position independently of the arm K. `As shownin-Figs. 5 andythe arm K1 is pivotally` mounted on a stub shaft K1fastened by a nut `K8 tothe frame B so that, like the arm K, it extendsrearwardly alongside the bank of magazines when in its inactiveposition* and is provided with `a handle K9 whereby it maybe rockedmanually into and out of its forward active position. VBecause the rightside of the magazines do not diverge` outwardly from front to rear tothe same extent as the left side of the magazines (see the shape of thebase frame inFig. 5), and also in order that the arm K1 will clear the`bankuof magazines when lin its inactive position and yet be in magazinesupporting position when in `its active position, the arm K1 is fastenedto the shaft K1 by` a screw K10 extending lthrough ya hub portion AK11of the arm and having a reduced unthreaded end portion` K12 whichprojects -into axspiral groove K13`formed in the periphery of the shaftand eX- tending throughout one-half the circumference thereof (Fig. 6).Withthis arrangement, when the arm K1 is moved from the :full lineposition to the dottedline position in Fig; `5,\the screw K1o followsthe spiral groove K13 and shiftsV the arm K1 as awhole inwardly or tothe left toward the companion arm K, the screw K10 maintaining the arm Kin `itsactiveposition by banking against the end of the slot K13.Likewise when the arm K1 is returned to its inactive position,.the endAof the screw K10 followswthe groove K13 and shifts thearm'jas a "wholeoutwardly vor to the right,

A U-'shaped member/A8;-forjsupporting the magazine'separating plateEfis arranged flatwise with its crossbar welded to the'underside of the rear 'bar `A6, its arms extending forwardly and beingWelded to the center membersA". Hence, the baseframe is a lsimplebuilt-up structure of light-weight steel structural elements which maybe individually-machined, where machining is necessary, before fbeingassembled and welded into a unit.

The rear-bar A6 of the base frame is equipped at its opposite lendswiththe pins A2, previously mentioned, which engage in notches formed inthe side plates A3 to permit the pivotal movement of the base frame inthe spreading of the magazines. A cut-out A15 is provided in the forwardedge ofthe rear bar A6 to receive the aforementioned centrally locatedfore-and-aft reinforcing-bar on the underside of the magazine. TheU-shaped vmember A8, which supports the rear end of the'y magazineseparating plate F, has grooves A11i formed in the top surface of itstwo arms `to ,provide 'bearings'for'the pins F1 projectinglfrom oppositesides of the plate and which permit t1f1epivota1 movement of the platein raisingand lowering the magazine. In order to provideI clearance forAthe plateF and cam G when in their inactive positions, so that themagazine `will rest on the side members A4 of the base frame, boththelfront and rear -walls of the channel member ,A5 are out away as atA1. v TwornembersA25 are Welded to the channel member A5 at its'opposite ends and extend forwardly therefrom, lbeing formed Aat their'iront ends withupstanding shoulders or lugs A10 adapted to engage theVforward edge 'o f the front magrazine cross'b'ar *a2 to hold'themagazine in position on the base frame.

As best shown linFigs. l and 8, the banking screws A13 are threaded uptight against thebottom 'of the bosses\A11, whe'reas the screws'A12 in the respectivebase frames are threaded downwardly into the bossesthe screws A12 beinglong enough toextend above thertop of the magazines suppoted on saidbase'tframes into engagement with the banking screws' A13 of the baseframe next above.

It` willv now be apparentthatthe present -inl vention represents a-distinct advance over the construction of the present commercialmachine. The improved base frame" is structurally amore simplied unit,and this, in addition to the fact that the elements are structuralshapes, enables a reduction in 'the' weight of the base frame structureequal to approximately one-half `the weight 'of a, standard cast ironbase frame. f Yet such reduction in weight carries with it no sacrificein strength. 'I'he substantial reductionin the weight ocf the shiftframe unit` has resulted in cutting down the time required for themagazine shifting operation due to the fact that the shift unit' lcan beaccelerated and decelerated with `less effort and clash. Furthermore itpermits a more satisfactory counterbalancing of the shift frame unitandv reduces the possibility of damage to the parts in the eventAsomething intervenes to obstruct its movement; Because of their size;the individual elements making up the improved basev frame are mucheasier to handle for machining and finishing, and should oneelement beaccidentally rendered unusuable, that element alone is affected.Moreover, the individual elements,` and the base frame vas a whole,being made of steel, have more life and are tougher than the cast ironstrutturev of theart. Whileit is preferred to use steel structuralelements and weld them into a unitary structure, obviously the elementscould be madeof otherma'terials or alloys having the desiredcharacteristics of adequate strength and lightweight; and inany case,the elements could be joined together otherwise than by welding.

As regards the improved. magazine spreading and separating mechanisms,here again simplicity of design and construction are combined inproviding for rapid and easy operation'. The magazine spreadingmechanism is mounted in the machine frame as rotation of the magazinesupporting arm to obtain the' increase in mechanical adthe art, and,`as`already stated, many variations and modifications, ofthe preferredembodiment of the invention shown in the accompanying drawings may bemade which will still be -comprised within its spirit.` It is to beunderstood, therefore, that the invention is not to `be limited toanyparticular form or embodiment except insofar as such limitations arespecified in the appended claims. t
